Digestion promoting leech culturing feed and preparation method thereof

Abstract

The present invention discloses a digestion promoting leech culturing feed and a preparation method thereof. The feed comprises the following raw materials in parts by weight: dog meat powder 140-150 parts, corn germ meal 80-90 parts, oat hulls 15-20 parts, garlic leaf meal 10-15 parts, chicken bone extract 5-7 parts, seaweed salt 0.4-0.6 part, cinnamomum tamala extract 0.1-0.2 part, black fungus polysaccharide 0.04-0.05 part, malts 2-3 parts, semen coicis 1-2 parts, dilute milk 20-30 parts, EM zymophyte 0.1-0.2 part and liquid protein concentrate 0.7-0.8 part. The finished products of the digestion promoting leech culturing feed are in micro powder states, are easily dissolved or suspended in water, can adsorb onto sponges to conduct feeding, are easier to be taken and digested than the feed of ordinary big grain sizes, and are easy in storage and long in shelf life.

Description

technical field [0001] The invention relates to the technical field of aquatic feed processing and preparation, in particular to a digest-promoting leech breeding feed and a preparation method thereof. Background technique [0002] Leeches, commonly known as leeches, are a kind of precious Chinese herbal medicines, which are recorded in many medical classics in ancient my country. It is recorded in the "Compendium of Materia Medica" of the Ming Dynasty: water frogs "mainly drive away bad blood, trace blood, moon closure, and accumulate under broken blood. Childless, Lishuitong...heals wounds, falls, and animal blood." Modern medical research shows that leech salivary glands contain an anti-coagulant substance—hirudin, which can be widely used in medical fields such as replantation of severed limbs and inhibition of cancer cell growth. With the application and improvement of modern biotechnology, the extraction and processing of hirudin and the clinical application of medicin...

AI Technical Summary

Problems solved by technology

Judging from the currently mastered leech breeding technology, the current leech farming mainly uses animal blood, earthworms, snails, river mussels, etc. as edible feed. These feeds are not processed to a high degree, and the absorption and utilization efficiency of nutrients is low. The breeding cycle is long, the growth is not good, and it is easy to lead to the occurrence of disease and death

Due to the lack of suitable feed, the quality and output of leech cultivation have been greatly affected. Therefore, it is urgent to develop a leech feed with high breeding efficiency and high added value.
